Recently the Kobo app for the PlayBook was updated and simply stopped working for many PlayBook users. The app, the only eBook store available on the PlayBook, today has finally been updated and should be working again for all users. The previous version was said to only be a problem for those running PlayBook 2.0, though the app wouldn’t work for many who haven’t upgraded to the developer release. The release notes for the app don’t give any hint as to what was changed, or why it suddenly works again. It’s better than nothing, but it’d be nice if Kobo would communicate a bit more to it’s users.
